Overview
The TLC5971PWP is a 12-channel, 16-bit Enhanced Serial Pulse Width Modulation (ES-PWM) RGB LED driver manufactured by Texas Instruments. It operates within a supply voltage range of 3.1 V to 3.5 V and features an internal linear regulator. The device utilizes a 20-pin HTSSOP package and supports surface-mount installation. Key electrical specifications include a maximum power dissipation of 3.121 W and a maximum supply current of 4 mA. It functions across a temperature range of -40°C to +85°C.
Feature Summary
- Integrates 16-bit ES-PWM technology for high-resolution grayscale control of RGB LEDs.
- Includes built-in fault detection mechanisms such as LED open detection and error flagging.
- Features an internal gray scale clock to simplify system timing requirements.
Applications
- RGB LED display systems
- High-fidelity lighting control applications
Procurement Notes
Verify the specific package variant, as the PWP suffix denotes a 20-pin HTSSOP tube packaging. Confirm that the 3.1 V to 3.5 V operating voltage aligns with your system design, as this component includes an internal regulator requiring precise input levels. Ensure compliance with RoHS directives and check moisture sensitivity levels for proper storage handling prior to assembly.
Selection Notes
Select this component when high-resolution 16-bit color depth is required for RGB LED matrices. It is suitable for designs needing integrated PWM generation without external microcontroller processing overhead. Consider the 20-pin HTSSOP footprint for space-constrained PCB layouts. Verify thermal management capabilities given the specified power dissipation limits in enclosed environments.
Part Context
This part belongs to the TLC5971 series from Texas Instruments, specialized for driving complex RGB LED arrays. It distinguishes itself through enhanced serial pulse width modulation, offering superior brightness uniformity compared to standard PWM drivers. The integration of fault detection enhances system reliability in critical display applications.
Replacement Considerations
The TLC5971RGER serves as a pin-compatible alternative in a VQFN-24 package. Verify interface compatibility and thermal performance differences when substituting between the HTSSOP and VQFN form factors.
